lingxingic · EEPROM · SOP-8

24C128 from lingxingic, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Device address input bit 0. Used for hardware addressing so up to 8 devices can share the same I2C bus. Internally pulled down to GND if left floating.
2 A1 input Device address input bit 1. Used for hardware addressing so up to 8 devices can share the same I2C bus. Internally pulled down to GND if left floating.
3 A2 input Device address input bit 2. Used for hardware addressing so up to 8 devices can share the same I2C bus. Internally pulled down to GND if left floating.
4 GND power_in Ground reference for the device.
5 SDA bidirectional I2C serial data. Bidirectional, open-drain output requiring an external pull-up resistor; may be wire-OR'd with other open-drain/open-collector devices on the bus.
6 SCL input I2C serial clock input. Data is latched into the EEPROM on the rising edge of SCL and shifted out on the falling edge. Supports 400 kHz (1.8V-2.5V) and 1 MHz (2.5V-5.5V).
7 WP input Write protect. Tie to GND to allow normal read/write operations; tie to VCC to hardware write-protect the entire 128K array.
8 VCC power_in Supply voltage, 1.8V to 5.5V operating range (6.25V absolute maximum).

  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: 24c128-etched.step / 24c128-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 24c128.step / 24c128.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: lingxingic datasheet (17 pp, sha256 26039a8ba553e8a4, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
